. T all whom it may concern:

Be it "known that I, PHILIP HAAS, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Water Closets; and I do hereby declare the following to be a full,

clear, and exact description of the invention,

such as will enable others skilled in the art" to which it appertains to make and use the same. I

My invention consists in the novel features hereinafter described, reference being had to the accompanying drawings, which illus trate one embodiment of the same, selected by me for purposes of illustration, and the said invention is fully disclosed in the foldischarge passages ofthe rim flush, which would result in an unnecessary consumption of water, a maximumsupply of water being provided which may be independently furnished to the rim flush for the purpose of insuring the normal flushing discharge through all of the discharge passages of the rim, when desired. Iconveniently effect this. action of the flushing; rim by providing the rim flushing passage, preferably at opposite .4o sides of the bowl and between the front and rear portions thereof with dams located in the bottom of the passage and being of less heightthan the passage itself.' In connection with the rim so constructed I provide a minimum water supply passage adapted to supply water to the rear portion of the rim in small volume suilicient to discharge through the discharge apertures of the rim in rear of the dams, without overflowing the solatter, thus cofining the minimum water supply to the rear portion of the bowl, and I Application filed March 21,1922. SerialNo. 545,407.

also provide a maximuniwater supply passage adapted to discharge a largervolume of water into the rim passage which will over.- fiow these dams and supply water to all of the discharge openings in the rim. The bowl is also provided with a ventilating jet at the bottom, in line withthe discharge passage of the bowl. As --this-jet.is.formed of metal I connect the jet supply pipe to the porcelain bowl by means'of a .spudin such manner as to make a tight joint, andthis spud is provided internally with anadjusting device removable from the exterior without interfering with the water connection, the said removable device beingprovided with throttling apertures for adapting the jet to the particular water pressure available in connection with the closet. adjusting devices are furnished with throttling apertures of different size,'or the throttling apertures therein maybe increased in size and number for the purpose of adapting the jet to the particular water pressure available, and the throttling device may also be withdrawn for cleaning if desired or necessary. My invention also comprises means which bringinto action simultaneously the water supply for' the jet and the minimum water supply to the rim flushing passage for the purpose of ventilating the bowl and wetting the rear portion of the wall thereof when desired, while holding the main or maximum sup ly for the rim flushing passage closed. hen desired the maximum supply to the rim flushing passage may be brought into operation simultaneously with the supply to the jet and simultaneously with the operation of the minimum supply if desired, so as to secure a very complete and thorough flushing action.

In carrying out my invention, I prefer to employ a controlling valve mechanism for the various water passages, such as is herein shown and described, said valve mechanism being adapted to be controlled either manually or by the depression of the seat, but preferably manually, and operating so as to produce the proper sequence of ventilating and flushing operations.

According to my invention, the bowl is also provided at its rear portion with a ver- These ion tically disposed water passage leading downwardly from the maximum water supply for the rim flush and discharging upwardly and rearwardly into the main discharge of the the the bowl, for the purpose of facilitatin flushing action and cooperating wit other flushing elements.

In the embodiment of my invention herein shown and described, which has been selected by me for purposes of illustration. 1 representsthe closet bowl, which in this instance is of the type adapted to fit against the wall and be supported therefrom without any connection with the floor, although it, is to be understood that my invention is equally applicable to the type of bowl which is supported from the floor. In the present instance the bowl is provided with an attaching flange, 2, adapted to be connected by threaded studs, 3-3, andnuts, 4, 5, with a flange, 6, secured to or preferably forming a part of the vertical soil pipe, 7, and surrounding the lateral aperture, 8, in the pipe communicating with the discharge passage of the bowl, a tight joint between the bowl and the pipe, 7, being effected by means of a sleeve, 9, and gasket, 10, for example." The bowl itself is provided with a rim flushing passage, 11, extending entirely around the bowl and provided at intervals with discharge apertures, 12, in the usual manner. 13-13 represent vertically disposed obstructions or dams, see Figs. 2, 3 and 6, located in the bottom of the rim passage, 11, and being located at opposite sides of the bowl 'between the front and rear portions thereof,

term the maximum water supply passage for the rim, and which communicates with the rim by an aperture, 15, see Figs. 2 and 6. The transverse maximum supply passage, 14, connects with a discharge pipe, 16, projecting from the body of the controlling valve mechanism, indicated at 17, and I prefer to connect the valve mechanism to the bowl so asto make a tight joint with the pipe '16, and support the valve in operative position with respect to the bowl by means of, a hollow clamping rod or tube, 18, which has a threaded connection within the valve body, as indicated at 19,.and extends axially through the pipe, 16, and through the transverse passage, 14, from one side of the bowl to the other. The ipe, 16, is provided with a flange, 20, and g sket, 21, to engage the side wall of the bowl adjacent to the passage, 14, therein and the other end of the hollow clamping tube, 18, is provided with a clamping'nut, 22, and gasket, 23, which ening a tight joint at opposite ends of the transverse passage, 14, of the bowl, and securely holding the valve mechanism in position in operative relation with the bowl. 1 The tubular clamping device, 18, is provided adjacent to the center of its length with a, discharge aperture, 24, which is directed toward the aperture, 15, which forms the communication between the maximum water supply passage, 14, and the rim passage, 11, and means are provided, as hereinafter described, for introducing'the minimum water supply through thehollow clamping device, 18, which forms the minimum supplypas: sage, so that the water will be discharged through the aperture, 15, from the tube, 18, into the rim passage in suflicient quantity to supply the discharge passages, 12, in rear of the dams, 13, without overflowing the dams.

*of the bowl which is separated from the rear portion of the bowl proper by a vertically disposed partition, 26, in which is formeda vertical water passage, 27, having a discharge, 28, at its lower end directed upwardly. and rearwardly into the main distical passage, 27, communicates at its upper end with .the transverse -maximum supply passage, 14, before described, and will receive water therefrom diiring the maximum supply to the rim flush. The lower part of the bowl is provided with a ventilating jet, .the construction of which is illustrated in detail in Fig. 7.

Where jet connections have been used with 25 represents the main discharge passage 120 charge passage, 25, of the bowl. The verearthenware closet-bowls, such as is illustrated herein, for example, considerable difficulty has been experienced in making the proper connections for the reason that an aperture of the necessasmall diameter for the jet cannot be m e practical in the earthenware, and there is considerable difiiculty in connecting a jet nozzle in such a manner as to efi t a tight joint and yet permit of making the necessary pipe connections from the outside and more particularly securing the desired regulation of ,the jet 1 in proportion to the water supply, the pressure of which varies materially in different installations. Obviously a jet which would operate satisfactorily with a water pressure of or pounds is not suitab-lefor an installation where the water pressure is 60 to 80 pounds, and vice versa. In accordance with my invention, I provide the lower part of the bowl ata point in alignment with the discharge passage, 25, with an aperture, 29,

' of considerable diameter, say if", for ex ample, which can .be readily molded in the earthenware. The jet nozzle comprises a metallic spud or sleeve, 30, provided at its inner end with a lateral flange, 31, which preferably engages a recess, 32, countersunk 1n the earthenware at the inner end of the aperture, 29, so as to avoid any projection. on the innerside of the bowl. The spudv or sleeve, 30, is provided with an exteriorly threaded portion,-indicated at 33, to receive a rubber washer, 34, a metal washer, 35, and a nut, 36, by means of which the spud is securely clamped to the earthenware and firmlyheld in position. In order to supply water I to the interior of the sleeve or spud, it is i provided with lateral inlet apertures, 37, be-

low the clamping nut,'36, and "a water connection, 38, is provided which has a sleeve' portion, 39, adapted to surround the spud, and carryinga washer at either end, as indicated at 4041, the sleeve member, 39, being held in position by a cap nut, 42, which engages the lower end of the spud. .The sleeve member, 39, of the water connection;

'38, permits it to be adjusted around the axis of the spud, as will be readily understood.

For the purposeofregulating the passage of the water \through the jet according tothe pressure of-the water sup-ply, I preferably employ a detachable regulating stem, one of which is illustrated in detail in Fig.

8. This comprises a shank portion,.43, of

less diameter than the interior: of the spud, a perforated head, 44, at one end of the said shank, and a threaded screw portion,- 45, having a slot or other means by whichit can be turned, the threaded portion being adapted to'engage an interiorly threaded portion at the outer end of the spud, as clearly shown. in Fig. 7. 'When screwed into its proper position, this device will have the inner face of the perforated head, 44, flushwith the face of the flange, 31, of the spud,

and the head 44 is provided with a plurality of apertures of such number and size as to secure the desired results with a given water pressure. I prefer to provide a plurality of these adjusting devices having'their heads 44', rovided with apertures of different sizes,,accordin to the usual water supply pressures am able in places where these closets are to be installed. In setting the closet, the operator will select a regulating device suitable for the required water pressure, and when it is placed in position the jet will function properly with that pressure If it should be found that the correct pressure is either greater or less than that for which the dev ce was originally set, it is only necessary to remove the cap, 42, and take out the adjusting device and insert/another, theholes in the head of which are of the required size. Obviously if ,the operator was not providedwith afull set,of these adjusting devices, the .jet couldnevertheless be readily adjusted by increasing the size of the apertures in the head if the pressure was too low to give the desiredresults, or by soldering up certain of the apertures in case the pressure was too great for the particular adjusting device installed, but I prefer to provide the jet with the particular adjustmg device having its head, 44, drilled with v and the earthenware bowl, and that the water connections for the jet are entirely outside of the bowl and readily accessible and that the 'means .herein described for regulating the jet are also readily accessible from the exterior of the Jpowl for adjustment .or repair.

As before stated, my invention comprises means for simultaneously admitting water to the jet for ventilating purposes and to the minimum water supply for the rim flush, for the purpose of wetting down the rear portion of the wall of the bowl during the operation of the jet as a ventilating device.

This may be accomplished by the depression of the seat in a well known way, but I have found that-such automatic actuation results a very frequently in a great waste of water,

and where the water service is metered, as is now the case in'many large cities, it is particularly desirable to avold unnecessary consumption of water. I prefer, therefore, to.

effect this operation ofthe closet, as well as the subsequent flushing operation by a. manual device, although I wish it understood that the operation may be controlled, autoa matically by the seat,.if desired, In eflt'ecting the control and proper distribution of the water for the prellminary action of ventilating and wetting down operation, andfor thesubsequent flushing operation, I prefer to employ a valve mechanism such as is illustrated herein. In the form shown, 17 represents the main body of the valve casing,

' by a valve, 63, also carried on the valve which is provided internallywith a vertical partition, 47, having a threaded aperture formed therein to receive a detachable sleeve,-

48, which is screwed therein and which carries at its front ,end a lateral diaphragm supporting flange, 49. The front portion of the valve casing is provided with a' detachable cover, 50, between which and the-main body is a diaphragm, 51, the edges of which are clamped between the cover and the main body of the valvecasing. The central portion of the diaphragm carries a reciprocating valve stem, 52, secured to the diaphragm andextending through the sleeve, 48, the

forms the back pressure chamber of the valve mechanism. The rear portion of the valve body is provided with an inlet aperture, 57, extending through a threadedboss, 58, to which the water supply pipe may be secured, and within the aperture inside of the boss, 58, I preferably provide a screw sleeve, 59, provided on its inner end with the valve seat, 60, adapted to be engaged by a valve, 61, carried on the valve stem, 52, when the latter is in its innermost position, as shown in Fig. 4. A similar valve seat, indicated at 62, is provided on the inner end of the sleeve, 48, and is adapted to be engaged stem, 52, when the valve mechanism is in the position indicated in Fig. 5, with the stem at its extreme outermost position. The

valve casing is also provided with a horizontal partition, indicated at 64, above which is formed the outlet chamber, 65, which communicates through apertures, 66, In the sleeve, 48, with the interior of said sleeve,

and whichis shut off from the inlet aperture, 57, by the horizontal partition, 64. In

this outlet chamber, 65,'I preferably form a spider, indicated at 67, see Figs. 4, 5 and 6, which is provided centrally with the threaded sleeveportion, 19, into which one end of ,theclamping tube, 18, is screwed, as hereinbefore described. The outlet chamber, 65,

is also providedfwith an outlet aperture into which the maximum outlet pipe, 16, is screwed or otherwise connected, as previously described. For the purpose of effecting a connection between the tube, 18, which forms the minimum supplypassage for the rim flush, and the water inlet chamber 68, of the valve mechanismfl find it convenient to drill a hole, indicated at 69, vertically through the spider,,67, and to insert therein an adjusting screw, 70, as shown, the valve casing being conveniently provided with a coaxial countersunk hole, 71, to receive a screw plug, 72, flush with the upper surface of the valve casing to prevent accidental disturbance of theadjust'ing screw, 70. The lower part of the passage, 69,'will afford a' direct connection between the water inlet chamber and the minimum water supply pipe, 18, which supply can be regulated by means of the adjusting screw, 70. r The cap or cover, 50,- of the valve is provided with a relief aperture for the back pressure chamber,

56, indicated at 7 3, and controlled by a relief valve, 7 4. This relief valve, as before stated, may be operated automatically by the depression of the closet seat, or, as in this instance, arranged for manual operation. To this end the relief valve is secured to a plunger, 75, having a disc portion, 76, at its outer end, which is normally held by a spring, 77, in engagement with a disc, 78, on

the handle, 79, these parts being maintained in position by a cap, 80, screwed into an aperture in the outer end of the cover, the plunger being provided with a small diaphragm, 81, to prevent leakage. The cover, 50, is also provided with a relief passage, indicated at 82, communicating by small pipe, 83, with the interior of the outlet chamber, in this instance through an aperture, 84, in the spider, so that on the opening of the relief valve, 7 3, the contents of the back pressure chamber can be discharged. The bottom of the water inlet chamber, 68, is provided with a conection, 85, for the attachmerit of a pipe, 86, leading to the fitting, 38, of the ventilating jet.

The operation of the apparatus is as follows: Assuming that the water inlet of the a of the valve being in the position indicated in Fig. 4, the inlet valve, 61, will be closed upon the seat, 60, so that no water'can enter the valve casing, it being understood that a suflicient quantity of water to fill the back pressure chamber, 56, is passed through the stem, 52, between it and the pin, 53, so that the initial pressure of the water is exerted against the outer face of the diaphragm, 51, which, having a greater area than that of .the valve, 61, the latter is held closed. By moving'the handle, 79, laterally in any direction, the back pressure valve, 73, will be opened, permitting the escape of water pressure of the water in the inlet pipewill immediately force the valve stem forwardly with the entering water and close the valve, 63, against the seat, 62, on the end of the sleeve, 48, thus shutting off all communication betweenthe inlet and the maximum supply passage, -1 6,'for the rim flush. The entering water will be discharged simultaneously to the jet through the connection, 85,

and pipe, 86, and also upwardly through the passage, 69, to the minimum supply passage, 18, for the rim flush, and the Water carried thereby will be projected,as shown in Fig. 2, through the lateral aperture, 24, in the pipe, 18, and through the communicating aperture, 15, in the rear wall' of the rim flush passage into the passage, 11, a small volume being delivered which will be held back by the dams, 13, and discharged through the. rearmost discharge apertures, 12, between said dams and the aperture, 15, to' wet down the rear wall ofthebowl while the jet projects a strong injector stream longitudinal y of the discharge passage, 25, carrying out of the bowl the water normally maintained therein to form the water 'seal, indicated by the dotted line in Fig. 2, and thereafter withdrawing large Volumes of air from the interior of the bowl and performing a perfect ventilating function. lhis ventilating function is under the control of'the user and maybe continued for any desired length of time by simply holding the handle in its deflected position.- It may be performed at any time and continued with the effect of ventilating the room in which the closet is located, or it may be employed for a few seconds only as may be desired, especially where economy of water is an object.

As soon as the handle is released it returns to normal position under the action of the spring, 77, upon the plunger, 7 5, and the relief valve is closed, whereupon pressure immediately begins to build up in the back pressure chamber, 56, by reason of the passage of water through the valve stem between it and the loosely mounted pin, 53, and the pressure acting upon the outer face of the diaphragm, causes a slow movement of the valve stem rearwardly toward its closing position. The first movement of the valve stem unseats the valve, 63, from its seat, 62, thus allowing water to pass through the sleeve, 48, and through the apertures, 66, in the lateral walls of the sleeve to the maximum water passage, 16, communicating with the transverse passage, 14, in the bowl, and thus giving a full volume of water which enters the rim passage, 11, through the aperture, 15, in sufiicient volume to overflow the dams, 13,. and to force through all of the discharge apertures, 12,

and all the wayaround the bowl with initial pressure, while a portion of the water passes through the vertical passage,'-27, and is dis- 7 I charged upwardly and rearwardly through the outlet, 28, thereof, in substantially the same direction as the. jet to assist the action of the jet and flushingfwater in driving g out the entire contents of the bowl and thoroughly cleansing the same.- As the valve, 61, approaches its seat,"60, the supply of water is c'ut oif gradually, thus stopping the flushing action and allowing the last portions of the water to ent r under restricted pressure so as to insure he refilling of the owl to the point indicated by the dotted line in F ig: 21to seal thesame. It will thus be seen that when the valve mechanism is'operated by the lateral movement of the handle, 79, the water is admitted simultane-i'" ously to the jet and to the minimum supply,

passage for the rim, while the connection with the maxiinum supply passage is mainthus giving the fullest possible flushing operation during the return movement of the valve.

88 represents the usual closet seat which isprovided with hinge members, 89, pivotally connected to cars 5 formed on the securing nuts 5 for the rear flange of the bowl, as shown in Fig. 2. '90 represents the seat cover having a hinged member, 91, also pivotally connected by the same bolt, indicated at 92, to the ears, 5 and the seat cover is preferably provided with bufl'ers of rubber, indicated at 93, to engage the upper surface of the rear flange of the bowl,

as indicated in dotted lines in Fig. 2, when in vertical position.
